Degritter brand ultrasonic record cleaner

I received notification yesterday that the Degritter ultrasonic record cleaner is finally making it into production. I have been watching the company for about a year, as the cleaner has moved from prototype to beta testing , and now to a limited production of the finalized (we’ll see ;-) version. The design is excellent, eliminating my reservations about the high-priced (around $4,000) ultrasonic cleaners, at a little over half their price (just over $2,000, last I read). The Degritter uses 120kHz as it’s ultrasonic frequency, and features water filtering and disc drying. It also looks cool, like a 1950’s toaster! Details available on the companys website.

Nice to hear from you, and that you’re still cleaning.

The thing about higher frequency is that the wave length is shorter. A 40KHz wave is about 1.5" long, a 120KHz wave is 0.5" long. The significance of this is the space necessary for the US wave to develop. If the space (record to tank wall) is less that the wave length, then cleaning is compromised. And don’t forget to factor in a margin for warped records, so those numbers are an underestimate.

Bottom line is a 120KHz machine can have a smaller tank. If it meets spec, and truly generates 120KHz. Which is why it’s a good idea to buy lab grade equipment like the PH60 - you know what you are buying, and you can trust it to meet spec, this year and next.

The first thing I did when I bought the PH60 was to test for damage. It doesn’t, unless you overheat (50C) the chemistry - then records warp, but the grooves remain undamaged. At least, not with my equipment, which includes an air bearing turntable and a Koetsu.

I have cleaned some 3000 records, most of them twice, some many times. No detectable damage from US. YMMV, but I doubt it.
